BALlNG-PRESS.

SPECIFICATION formingpart of Letters Patent No. 688,255, dated December 3, 1901.

Application filed August 18, 1901. Serial No. 71,920. (No 'model.)

To all whont may concern:

Be it known that I, MARVIN MEAD, a citizen of the United States of America, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented certain new and usef 111 Improvements in Baling-Presses; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in baling-presses.

In my improved construction of press the baling-chamber reciprocates and telescopes over the plunger or abutment, which remains relatively stationary. The baling-chamber and the plunger-head also preferably occupy an inclined position, whereby the-power required to accomplish the two strokes is practically equalized, making the pull substantially uniform in both directions. The balingchamber moves up the incline on the return stroke, while its forward or working movement is accomplished partly by gravity, thus lessening the power ordinarily required to accomplish the working stroke. Hence by virtue of my improved arrangement the power required to accomplish the return stroke is i'ncreased,whi1e the power ordinarily required to accomplish the working or baling stroke is diminished, thus equalizing as far as possible the two strokes and to this extent rendering the pull even and uniform.

Another advantage of my improved construction is that a large automatic feeder may be employed without obstructing the hopper-entrance when the material to be baled is placed therein,since when the baling-chamber is at the limit of its forward stroke the hopper is below or forward of the feeder long enough to permit the placing of a charge of material therein, after which the hopper is returned with the baling-chamber to a position in the path of the feeder, which then acts to force the charge from the hopper into the baling-chamber before the next forward stroke begins.

Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a side elevation of my improved baling-press, the forward position of the baling-chamber being indicated by dotted lines. Fig. 2 is a cross-section taken through the haling-cham ber on line 00 at of Fig. 1, viewed in the direction of the arrow. Fig. 3 is a side elevation of the baling chamber and the operating-pitman connected therewith. Fig. 4 is an end elevation of the same. Fig. 5 is a top View of the apparatus with the baling-chamber and the abutment or stationary plunger removed.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a frame which is relatively stationary during the operation of the press. This frame has a triangular appearance in side view, being provided with upper and lower bars 5 and 5. Mounted on the lower bars 5, one on each side, is the shaft or axle 6, upon Whose extremities are journaled the ground-wheel 7. Upon the upper frame-bars 5 which are preferably composed of angle-iron, is movably mounted the balingchamber 8, whose lower frame-bars 8 are provided with antifrictional rollers 9, which engage the stationary frame-bars 5, the latter forming a track for the reciprocating balingchamber. To the forward extremity of the frame 5 is secured the stationary abutment or plunger 10, which enters the baling-chamber as the latter is moved forward or made to perform the working stroke. Above the baling-chamber and mounted thereon to reciprocate therewith is the hopper 12. The reciprocating movement is imparted to the baling-chamber by means of pitman 13, operatively connected with the baling-chamber at its forward extremity, as shown at 14, while its rear extremity is connected with a crankpin 15, carried by two gears 16, journaled on the framework 5. The gears 16 are rotated by meshing pinions 17, made fast to a shaft 18, provided with an operating-pulley 19, which may be connected with any suitable power.

The feeder mechanism is not claimed in this applicationandwill be' briefiy described-only.

This mechanism is-mounted on the stationary frame by means of brackets A, in whose upper extremities are slidably mounted the feeder-rods, carrying a slidable cross-head O, engaged by buffer-springs 'D, surrounding the rods B. The feeder proper is mounted on the cross-head and designated by the reference character E. This feeder-head is directly in line with the hopper when the baling-chamber is at its rear limit of movement. The feeder is operated, as shown in the drawings, by two levers H, fulcrumed on the frame 5 at I. The forward extremities of these levers are connected with the feeder-rods l3, while their opposite extremities are connected with depending arms J, attached to the frame by links The lower extremities of the arm J are connected by a cross-bar L, which lies in the path of the rear extremity of the pitman during a portion of its stroke. As the crank-pin 15 moves upwardly when in the pos'ition shown in Fig. '1, the lovers 14. will be actuated to force the feeder downwardly until the forwardly-traveling pitman releases the .cross-bar L. This occurs in time to allow the feeder to return to its normal position by virtue of :the recoil of the springs D before the chamber .8 moves forwardly.

When my improved press is moved from one place'to another, the frame 5 is mounted on four ground-wheels 7. Before beginning the baling operation the forward pair of ground-wheels (not shown) is removed, allowing the corresponding extremity of the frame to 'drop to the position shown in Fig. 1, increasing the inclination of the track upon which the baling-chamber is slida'bly mounted. When in this position, the upper extremity of the bale-chamber frame is suffic'ient'ly elevatedto discharge the bales at a height of eight or nine feet above the ground, if desired. By means of my improved construction'the bales are delivered away from the stack.-

At'the upper extremity of the bale-chamber frame a platform 20 is hinged and supported by rods 21.

From the foregoing description the opera ber Swill be reciprocated through the instrumentality of the pinions, the gears, and the pitman, by virtue of the construction and arrangement of parts heretofore described. During this'forward movement the bale-chamber telescopes and incloses the abutment 10,

Power beass ss which acts on the material therein with the required force to perform-the baling function. While the bale-chamber and hopper are in their forward position, as shown by dotted lines in Fig. 1, and consequently beyond or forward of the feeder, a charge of materialis placed in the hopper while the latter is directly above the abutment or stationary plunger. As soon as the bale-chamber returns to its opposite limit of movement the feeder acts to force the charge of material into the balingchamber, after which the latter is moved forwardly, as before.

Having thus described my invention, what I claim is-- 1. In a baling-press, the combination with a suitable fixedframe, of an open-ended baling-chamber mounted to reciprocate on the frame in an inclined plane, means for operat ing said chamber, and a relatively stationary abutment or plunger, in ,alinement with the baling-chamber and arranged to cooperate therewith. I

2. The combination with a suitable fixed frame and a feeder mounted thereon, of a reciprocating baling-chamber provided with a hopper and means for operating said feeder when the baling-chamber is at its rearward limit of movement, and a relatively stationary abutment or plunger, in alinemen-t with the baling-chamber, and arranged to\eooper ate therewith, the arrangement beingsuch that the hopper is directly above the abutment when the baling-chamber is at its forward limit of movement.

3. In a baling-press, the combination with a suitable fixed frame and a feeder mounted thereon, of a 'baling-chamber mounted to reciprocate on the frame in an inclined position and provided with a hopper, and a relatively stationary abutment or plunger arranged to cooperate with the baling-chamber, the arrangement being such that the hopper is beyond or out of the path of the feeder, long enough during each reciprocation, to permit the charging of the hopper with the material to be baled.

4. In a baling-press, the combination with a suitable fixed frame, of an open-ended baling-chamber mounted to reciprocate thereon in an inclined plane, means for operating the baling-chamber, and a relatively stationary abutment or plunger located at the lower extremity of the chambers travel and arranged I to cooperate therewith, whereby there is a tendency to equalize the power required to accomplish the two strokes,and make the pull uniform substantially as described.

5. The combination with a fixed frame having an inclined track and an abutment or plunger mounted on said frame at the lower extremity of the track, of an open-ended bal ing-chamber mounted to reciprocate on the said track and cooperate with the abutment and means for operating thebaling-chamber. 6. The combination with a frame having an inclined track and a fixed abutment or plunger at its lower extremity, of an open- In testimony whereof I aflix my signature ended baling-ehamber mounted to reciproin presence of two Witnesses.
